Description

вращательного движени ведущей полумуфте 1 под действием момента сопротивлени на ведомой полумуфте эксцентричные щейки 2 и 3, враща сь, удал ютс от кривощипных пальцев 6 и деформируют таким образом пружины 8 раст жени до тех пор, пока суммарный момент со стороны деформируемых пружин не уравновеситс с моментом сопротивлени . В дальнейщем происходит синхронное вращение ведущей и ведомой полумуфт.the rotational movement of the leading half coupling 1, under the action of the moment of resistance on the driven half coupling, the eccentric cheeks 2 and 3, rotating, move away from the curvature fingers 6 and thus deform the extension springs 8 until the total moment from the deformable springs is balanced with the moment resistance In the future, there is a synchronous rotation of the leading and driven coupling halves.

В случае перегрузки ведома полумуфта; останавливаетс , а коленчатый вал продолжает вращатьс , периодически деформиру пружины 8.In the event of an overload knowing the half coupling; stops, and the crankshaft continues to rotate, periodically deforming the spring 8.

При устранении перегрузки на ведомом звене привода обе полумуфты вращаютс синхронно , а эксцентричные щейки 2 и 3 занимают определенное положение по отнощению к пальцам 6.With the elimination of overload on the driven link of the drive, both coupling halves rotate synchronously, and the eccentric cheeks 2 and 3 occupy a certain position with respect to the fingers 6.

Предварительна деформаци пружин 8 осуществл етс путем поворота пальцев 6 относительно осей своих концов 7 на определенный угол.The preliminary deformation of the springs 8 is carried out by turning the fingers 6 relative to the axes of their ends 7 at a certain angle.

Claims

Invention Formula

A safety elastic coupling containing a drive shaft mounted on the holders in the driven half coupling and connected with it by means of an elastic element, characterized in that, in order to increase the load capacity, the coupling half coupling is made in the form of flanges connected by two diametrically opposed curved fingers , and the elastic element is made in the form of springs, fixed by groups “and with each crankshaft finger, the driving shaft is made by crankshaft with eccentric grooves, the central ones of which are located coaxially one another and connected with springs fixed on one of the curved fingers, and the extreme eccentric cheeks are also coaxially one another and connected with springs fixed on the other curved finger, while the eccentricities of the coaxial cheeks of the drive shaft have a mutually opposite direction.
